... All reactants are needed for a chemical reaction to occur. As soon as one of the reactants is used up the reaction will stop. Any of the other reactant which is left is said to be “in excess”. It is the reactant which is totally used up which determines the mass of product formed. Worked example Wha ...

... The mole ration from hexane to Oxygen is 2 mol hexane/13 mol O2. Assuming stoichiometric equilibrium (there are no limiting or excess reagents) it takes 2 moles of hexane to react with every 13 moles of oxygen. This can also be done from reactants to products. Another mole ratio is 13 mol O2/12 mol ...
